I would replace the G3 iMac. Be warned that one of the only real reasons I say this is that I believe that the G4 iMac could be the nicest computer that apple has ever made. Really, I think that we need more information on what you like to do before we can make the assesment. How important is it to have power on the road for example. Anyways, I would still go for the iMac...

Thanks, I do mostly mild video and music editing and some Photoshop on high-def quality JPG images. And losts of MR + listening to music. I have a dual proc 1.42ghz G4 Power Mac but I need another computer to take some of the strain as my PM is on its last legs. In about 6 moths I'll probably buy a new iMac after one revision, or the mythic Dual-core PB. Thanks for your input.
